Subject [jira] Commented: (CASSANDRA-827) Add hooks that recognize when system KS is updated.
Date Tue, 06 Apr 2010 14:36:33 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-827?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12854004#action_12854004
] 

Gary Dusbabek commented on CASSANDRA-827:
-----------------------------------------

Not easily.  The current defsVersion needs to be known long before StorageService (and SystemMetadata)
is initialized.  I rearranged things so that DD keeps track of the initial version (from a
schema load or whatever) and passes it to SS.  Its all in v3-0009.

I also fixed a rename bug where the replication strategy wasn't getting reloaded (in case
it changed as a result of a drop+add).
